Problems solved by technology

Therefore, when the liquid crystal display is used to display fast-changing dynamic images (such as when watching a DVD film or playing a computer game) the user is likely to perceive poor display quality (for example, residual images or discontinuities are present on the screen).
However, since the overdrive table is fixed for each liquid crystal display and cannot be adjusted by t...

Embodiment Construction

[0032]FIG. 1 shows the preferred embodiment of a flat panel display device 100 according to the present invention. In this embodiment, the flat panel display device 100 is based on liquid crystal display (LCD) technology, and can be one of a LCD monitor, a LCD TV, and a digital TV with a liquid crystal display panel. However, it should be apparent to those skilled in the art that the present invention is not limited for application to the above examples and can be further applied to other flat panel display technologies (such as plasma display technology) and non-flat panel display technologies, etc., that employ overdrive techniques. As shown in FIG. 1, the flat panel display device 100 includes a control unit 110 (which is implemented as a micro-controller unit, or MCU), a display controller 120, and a memory 130. In this embodiment, the control unit 110 and the display controller 120 access the memory 130 through a bus 140. In this embodiment, the control unit 110 and the display...

Abstract

A method for adjusting display response time includes: a) providing an overdrive table; b) determining a response time setting status; c) changing the overdrive table according to the response time setting status; d) receiving video data; and e) with reference to the video data, looking up the overdrive table changed in step c) to obtain overdrive video data. A display device that implements the method is also disclosed.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority of Taiwanese application no. 096105216, filed on Feb. 13, 2007.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to flat panel displays, more particularly to a display device and method for adjusting response time of a flat panel display.[0004]2. Description of the Related Art[0005]Liquid crystal displays have advantages of slim size, lightweight, low power consumption, low radiation, and high compatibility with semiconductor manufacturing technology, and are widely adopted.[0006]Under varied alignment conditions of liquid crystal molecules, optical characteristics of light passing through a liquid crystal layer may be different. Hence, through application of electric fields to alter the alignment conditions of liquid crystal molecules, the amount of light that is allowed to pass can be controlled so as to generate different intensities of outputted light. A liquid crysta...
